To all whom it may concern:

Be it known that l, NIGHOLAS J. Wmuinn, a citizen oi the United Sta tee, residing-at Rockford, in the county of iinn'elmgo and State of Illinois, have invented certain and useful lniprovcmente' in Knitting chines, of which the 'l'ollowing is a spec I tion. l i

This invention relates to automatic 'knitting machines and refers particularly to circnlar knitting Il'ltLGliii'lCS adapted to form two or more kinds of web, as, for example, plainstitch web and rih-' 'titch Web.

One of the objects of this invention is the production of a inaehine adapted to knit a plurality oi lorms oi web with one set of iiecdies.

The inventioiii also relates to the other improvements in knitting; machines hereinalter set l'orth.

In the acconiipenyingdrawings, Figure 'l. is an elevatioirola portion of a circular knitting machine embodying the .l'catiires of my invention. Fig. is a vertical cei'itral sec- U011 therethrongh. Fig. 3 1s a horizontal crating the iorm ()Il needle represented in Fig. 7. sinlsiei-s,

In the production of rihetitch web by the machines now in use, a set 01' cylindorneodles and a set of dial needles are employed.

Fig. 101's a detail view of one of the .ll'lv invention contenn'ilates the prothict-ion of rib-stitch web by means of the set or heedlcs used tor the knitting ol' ])lLlH-Sl-1t0il Web, send needles being: divided. into two groups when rihetitch iahric is to be produced, or, in other words, COI'lliLlll ol' the neodles heii'ie; shifted from the iiecdle cy'lii'idcr to the needle dial. This result accomplish in" the use of the (i()lii.)l(.(%l'l(ll.(l needle ehown in Figs. .2 end 7. Said needle comprises what may be torniml a cylinde noodle end a dial needle, the shanks oi' whieh needles are prel} n'lounted a bed. 2 and a needle cylinder 13,

said cylinder having radial slots 4 therein, within which the cylinder jacks and the l nit ting; needles operate. A shalt 5 is rigidly supported in the framework above, and axielly alinod. with, the needle cylinder 3, and to the lower end oi said shat. lined a dial 6 provided with radial slots 7. Fixed to therod 5 above the dial 6 is ahead 8 consisting, in this instance, of two cylindrical members E) and ll) provided with alincd vertically ex tending groiwos ll. vv ithin the grooves 11 are pivotally mounted dial jacks 1,12 Figs.

and 10) having; openings K3 in their loner ends lor the reception oi the knitting needles to he hereinal'ter descri hcd.

The needle cylinder 3 is: provided at its up per end with an oi[twin-illywixtcnding animlar flange forming an inwariliy-inclin s i weir holder lied 14. having slots l5 therein in'whirh the wol'i-holdcin H are i'nountod. lloiatahly mounted. upon the hcd l i ithe weir-holder cam ring l7. Said cam ring; has an annular downwardly-extcnding flange It; to which is secured a bevel gear ring; ill. .ltotatably inoin'itcd upon. the, needle cylinder 3 is the knitting cam ring, 20 bearing: upon its inner periphmy knitting came of any common or preferred form for operating tine cylinder jacks. 20 (Fig. 2) an. annular ledg upon which the knitting biitts ol' the needle iiitlib rest, the knitting cams lining located in operative alinclncnt with said ledge. The space above the ledge 20, except at the point-at which the knitting); canes are situated, is open, its shown in Fig. 2, to permit the noodle jacks to rise, as will appe hcrcinz'il'ter. knitting earn ring 20 gidly secured to the bevel gear 19 by means of hangers 21.

Any suitable means may be provided for o 'ierating the dial jacks 12." In the prceel'it embodiment there are fixed to theweh-holder cam ring 17 two 'vortRally-extending posts 22 joined at their upper'ends by means of a cross arm 23, a hem-mg 24- heing provided in seid cross arm for the shaft 5. lower holder cam ring 17, and the dial-needle earns till and 26 are rotated by a bevel spur gear 27 fixed upon a shaft 28 and meshing with the bevel gear 19. Power to drive the various mechanisms of the machine may be applied to said shaft by means of the drive pulley 2t).

Thedouble-ended needle 30 (Fig. 7) employed in the embodimentherein shown of my invention virtually.eonsists of a cylinder needle 31 and a dial needle 32, the shanks of which needles extend at an angle with each other. In the shank of the cylinder needle 30 is formed an oilset 83 for the purpose of giving the needle shank sufficient thickness to prevent transverse movement of said needle in. the opening 13 of the jack 12.

As hereinbelpre stated, when rib-stitch Web is to be formed, certain of the needles are transferred from the needle cylinder to the needle dial. it is obvious that only the needles which are thus transferred need be of the double-eiuh d form shown. in Fig. 7, and that those which do not leave the needle cylinder may be of any common or preferred form, as, for example, the needle 34 shown in Fig. S. The needle 34 has a butt 35 for engagement by its operating jack. The relative arrangement of the needles 30 and 34- in the needle cylinder 3 depends, of course, upon the kind of rib-stitch web to he produced. in the knitting of. one-ahd -one web, for exrnmile, the needles 3t) and 34 alternate regularly in position in the grooves 4 of said cylinder. For the needles 3 1 provide jacks 236 having notches 37 int'heir upper ends of proper size to receive the dial needle portion 32, and for the needles 34 jacks 38 are provided having notches 39 there into receive the butts 35 upon said needles.

The means for elevating the needles 30 into thejaeks 12 in the head 8 will next be described. The means herein shown for this purpose is arranged to elevate one-half of said needles at a time by devices acting at opposite sides of the needle cylinder. Each of said devices eon'iprises a vertical post 40 rigidly supported in the marhine frame by means of a bracket -'ll Upon said post are slidably mounted two members 42 and 43 each in the form of a l'ialf-ring. The mem- 'l.)er 42- is provided with a sleeve 44 which is slidably mounted upon the post 4H. and the member 41; has a sleeve to filling loosely upon the sleeve '14. A pin in (Fig. i) lixed to the member 42% passes freely lhroughan opening 47 in the lower member 42 and en orts the member 43 in a lane above tie ed 2. Coiled; springs 48 liearing at their ends upon the upper ends of the sleeves 44 and and the bracket 41 tend to move the members 42 and 43 into their lowermostpositions as shown in Fig. 1 and at the left-hand side of Fig. 2. The jacks 36 are provided at their lower ends with butts 49 adapted to lie .an arm 53 which is arranged to have a pivotal movement with reference to said shaft for a purpose to appear hereinafter. l i'hen in the position shown in Fig. 1, the arm 53 hes in the path of a plunger 54 slidably mounted in a guide member 55 fixed. in the machine framei. Said plunger carries a pin 56 adapted tobe engaged by a cam 57 fixed upon the shaft28 for projecting said plunger against th 53 and thereby rocking the shaft 50' to e' the members 42 and 43. The pin travels in a-slot 58 formed in one side of the guide member 55, A spring 59 connected at one end to a stationary part of the framework and at its other end to a pin 60 fixed'to the plunger 54 restores said plunger to its 1 inward position after the cam 57 has acted. upon said plunger. A slot 61 is provided in the guide member 55 for each of the. pins 60. The arm 53 is arranged to be pivotally moved into and out of the path of movement of the plunger 54 by a pattern'meehanism (not shown) in order that the needles 30 may be transferred to the needle-dial 6 only at the pro er times. At a suitable point upon the roar shaft 50 is fixed an arm 62 carrying a pin 63. Pivotally mounted in the support mg frame is a detent 64 having, a notch 65 in its upper end adapted to. receive the in' 63 and thereby hold the members 42 an 43in the elevated position. A spring66 fixed to the detent 64 andto a stationary part of the framework tends to-move said detent into engagement with the arm 62. For moving the detent 64 out of engagement with saidarm I have provided, in this instance, a. bellcrank lever '67 pivoted in the supporting.

frame, one arm of which lever carries a nn 6S lying at oneside of the detent 64. he other arm of said bell-crank lever is eonnected with a pattern mechanism (not shown) of any common or )referred construc tion, 'for w thdrawing the detent at the proper time to permit the springs 48 to restore the needles 30 to the plain-stitch knitting position.

The needles 30 are not disengaged from their jacks 36 when raised into the rib-stiteh knitting, position. In order, however, to provide space for the yarn actedupon by the dial needle portionI-lil of said needles when in use l: have provided means for drawing; the upper ends of the jacks 36 outward a slight lists-nee, In Fig. 4:, 6?) indicates a member fixed to the webdioldcr camring l7,said incml'ior having a cam groove 70 in its lower side into which the studs 71. upon the upper ends of the jacks 36 enter. The 1" ()L'Il] of said rain groove is such that the jacks 36 engaged hy the member 69 in its rotation are moved outwardly slightly at the required time, said iachs rocking upon their butts ll),

The bobbin or bobbins a; are supported in hnr suitahle Way, as, for example, upon a cross bar 7) lixcd with relation to the crosshar 1 213 and therefore rotating with the hnit- .ting cams.

The yarn passes through eyes 73 upon one of the posts 212 and through a yarn carrier T ll lixed, to the \vcbdiolder ram. ring 17.

it motion-changing mechanism of any common or preferred form may be employed [or changing the inovomcnts ol the knittinc and ,rclrholdcr cinns from rotary to oscillatory', and vice versa. i

l have on'iittcd illustration of the, inians for throwing the needles into and out of action. in the formation of the heoland the too, as any desired mechanism may be employed 'l'or that purpose. Such. a mechanism is illustrated in Patent No. 4-7'Js,('l73, issued to inc on July 1), H92. in applying said mechanism to the present machine, the ra dtill v disposed suhiacks illustrated in the patent would be located below the plane of the members 4 2, the inner ends of said subjarlis cn zfagh'agr dim'nwarillyprojoctingr o);-
